Hive Partitioned Table - 尝试将数据从一个 table 加载到我的 Hive 中的分区 table 并得到 [Error 10044]*

Question

所以我有一个包含 20 列的 table，我创建了另一个分区 table - 使用 2 个分区值，现在当我尝试从包含 20 列的 table 加载数据时进入另一个分区 tables 我收到错误消息说我的分区 table 的列数多于 table 我从

插入数据

我的创建 table 语句：

  create table flight_data_parquet(
  YEAR INT,
  FL_DATE STRING,
  UNIQUE_CARRIER STRING,
  AIRLINE_ID INT,
  CARRIER STRING,
  TAIL_NUM STRING,
  FL_NUM INT,
  ORIGIN_AIRPORT_ID INT,
  ORIGIN_AIRPORT_SEQ_ID INT,
  ORIGIN STRING,
  DEST_AIRPORT_ID INT,
  DEST_AIRPORT_SEQ_ID INT,
  DEST STRING,
  DEP_DELAY FLOAT,
  ARR_DELAY FLOAT,
  CANCELLED TINYINT,
  DIVERTED TINYINT,
  DISTANCE INT)
partitioned by (Month INT, DAY_OF_MONTH INT)stored AS PARQUET;

-插入语句:

insert into table flight_data_parquet partition(month=1, day_of_month) 
select  YEAR,FL_DATE,
  UNIQUE_CARRIER,
  AIRLINE_ID,
  CARRIER,
  TAIL_NUM,
  FL_NUM,
  ORIGIN_AIRPORT_ID,
  ORIGIN_AIRPORT_SEQ_ID,
  ORIGIN,
  DEST_AIRPORT_ID,
  DEST_AIRPORT_SEQ_ID,
  DEST,
  DEP_DELAY,
  ARR_DELAY,
  CANCELLED,
  DIVERTED,
  DISTANCE, month, day_of_month
from flight_data_v2 where month=1;

我得到的错误是-

FAILED: SemanticException [Error 10044]: Line 1:18 Cannot insert into target table because column number/types are different 'day_of_month': Table insclause-0 has 19 columns, but query has 20 columns.

分区规范中的

month=1 partition(month=1, day_of_month) - 是静态分区并且值已指定，删除 month 来自 select 查询。只有 day_of_month（动态分区）应该在 select:

insert into table flight_data_parquet partition(month=1, day_of_month)  -- Month=1 is a static partition 
select  YEAR,FL_DATE,
  UNIQUE_CARRIER,
  AIRLINE_ID,
  CARRIER,
  TAIL_NUM,
  FL_NUM,
  ORIGIN_AIRPORT_ID,
  ORIGIN_AIRPORT_SEQ_ID,
  ORIGIN,
  DEST_AIRPORT_ID,
  DEST_AIRPORT_SEQ_ID,
  DEST,
  DEP_DELAY,
  ARR_DELAY,
  CANCELLED,
  DIVERTED,
  DISTANCE, day_of_month
from flight_data_v2 where month=1;
